Where DO I START? Your Bushnell telescope can bring the wonders of the universe to your eye. While this manual is intended to assist you in the set-up and basic use of this instrument, it does not cover everything you might like to know about astronomy. Although Northstar will give a respectable tour of the night sky, it is recommended you get a very simple star chart and a flashlight with a red bulb or red cellophane over the end.

Detailed Assembly No tools are required for assembly of your telescope. Remove all components from the carton and identify all components. It is a good idea to lay all the parts out in front of you before assembly. Since your telescope is a precision optical system the parts require careful handling—particularly the onboard computer, telescope, eyepieces, and various accessory lenses. SET-UP TRIPOD AND ACCESSORY TRAY 1.
Detailed Assembly (continued) M SELECTING AN EYEPIECE You should always start viewing with the lowest power eyepiece, which in this case is the 20 mm lens. Note: the base power of each eyepiece is determined by the focal length of the telescope objective lens. A formula can be used to determine the power of each eyepiece: telescope OBJECTIVE lens focal length divided by EYEPIECE focal length = MAGNIFICATION (e.g.
M ENJOYING YOUR NEW TELESCOPE 1. First determine your targeted object. Any bright object in the night sky is a good starting point. One of the favorite starting points in astronomy is the moon. This is an object sure to please any budding astronomer or experienced veteran. When you have developed proficiency at this level, other objects become good targets. Saturn, Mars, Jupiter, and Venus are good second steps to take. 2.
M HELPFUL HINTS 1. Your telescope is a very sensitive instrument. For best results and fewer vibrations set your telescope up on a level location on the ground rather than your concrete driveway or your wooden deck. This will provide a more stable foundation for viewing, especially if you’ve drawn a crowd with your new telescope. 2. If possible view from a location that has relatively few lights. This will allow you to see much fainter objects.

MMODE OVERVIEW OF PRODUCT Explore: The Explore Mode of Northstar provides the ability to explore various astronomical objects categorized by object type. These objects would fall under one or more of the following types of objects: Deep Sky, Planets, Constellations, and Stars. Each of these subheadings would also have subcategories of objects beneath their menu structure. (See Menu Tree for full list of menu functions and options.

M ALIGNING NORTHSTAR FOR THE FIRST TIME When you turn the telescope on a scrolling message will appear: The first display will then prompt you to level the telescope tube.
M ALIGNING NORTHSTAR FOR THE FIRST TIME (Continued) STEP 3: SET THE LOCATION The next screen will display: CITY will be flashing. By pressing the ENTER button, the display will change to: The country will be flashing. Again by using the SCROLL UP and SCROLLDOWN buttons and the ENTER button, the COUNTRY can be chosen. When the appropriate Country is found and the ENTER button is pushed, you would finally choose the city that you were closest to by pressing ENTER when it is displayed.
M ALIGNING NORTHSTAR FOR THE FIRST TIME (Continued) NOTE: THE USER WOULD JUST HAVE TO GET THE TELESCOPE POINTED RELATIVELY CLOSE TO NORTH. THE ALIGNMENT WILL BE REFINED AS WE PROGRESS. HOWEVER, IF YOU CAN FIND THE BIG DIPPER AND USE THE "POINTER STARS", FOLLOW THE ARROW ON THE ABOVE DIAGRAM TO THE NORTH STAR. THE NORTH STAR LIVES DIRECTLYABOVE DUE NORTH! After pointing the telescope NORTH and making sure the tube is still pointed level, pressing the ENTER button would complete the rough alignment process.
M USING NORTHSTAR FOR THE FIRST TIME After EARTH ALIGN, the display will then read: EXPLORE will be flashing. This indicates that you could choose other options by pressing the UP and DOWN buttons. However, let’s look at EXPLORE first. This is the default menu at this point because, this will most likely be the most often used mode. This is where the starfinding takes place. Select EXPLORE by pressing ENTER. SCROLL UP and DOWN to see what flashing menu choices you have. I always choose PLANET.
M USING NORTHSTAR FOR THE FIRST TIME (Continued) By pressing the BACK button, you move back to the previous level each time the button is pressed. Press the button three times and you are back at the main level menu. The display will read: SCROLLUP or SCROLL DOWN to select Press ENTER. This mode will take you through the best and brightest objects for each month. If you have done the ALIGN EARTH alignment and entered the date, it will automatically take you to the current month.
Catalog Index The following appendix information is more thorough information than that listed in the main instruction manual. For sake of space, the complete 20,000 object catalog is not listed. However, we have included the entire star list and the entire Messier object lists for your information. In addition, the constellation abbreviations are defined that are found in the Northstar system. 20.
